When booking HA award with AA, they provide AA confirmation code (six alphabets) and AA ticket #. After I asked, they also provided a separate HA confirmation code (six alphabets). (AA stated they don't have an HA ticket #, only AA ticket #.)

With all the above info, I cannot look up the ticket on hawaiianair.com. If I call HA, they can find the reservation. However, I specifically want to access the reservation and check-in online.

Checkmytrip.com also doesn't return any info using above confirmation codes.

Is it possible to find the reservation on HA.com and check in online?
